A bed that makes a horrible noise from Truewood furniture

I am very disappointed with the service I received from Truewood. I bought the bed in December 2021 and it was delivered in February 2022 because the factory was closed in December. The total of the bed and mattress was R26 380. The 1st week of the delivery, the bed started to make lot of noise, irritating noise. I went back to the shop to notify the sales person. After several visits, then the sales person said I must send an email to the manager Hannes who then send his team 4 times to my house to come and fix the bed. The last time he sent these men I said if they are unable to fix, they must take back this bed and refund me. The noise on the bed stopped for some time but the horrible one on the headboard is still there even today. The last time I called Hannes, he said that the noise is FACTORY ACCEPTED. I am still stuck with this bed with this horrible noise that comes from the headboard. We can't even lean on the headboard, and the sound on the bed is back. I am very DISAPPOINTED. Clientele lawyers tried to mediate and everytime they soke to him, he promised that he will call me but he never did.
